Hello autoconfers.
I've found this problem some times ago when extending the automake
testsuite. Sorry for only reporting it now.
$ cat foo.c
#include <stdio.h>
#include <stdlib.h>
#include <sys/wait.h>
int main(void)
{
int wstatus = system("kill -15 $$");
printf ("RETURN: 0x%x\n", wstatus);
printf ("WTERMSIG: %d\n", WTERMSIG (wstatus));
printf ("WEXITSTATUS: %d\n", WEXITSTATUS (wstatus));
return 0;
}
$ uname -mrsv
Linux 2.6.30-2-686 #1 SMP Sat Sep 26 01:16:22 UTC 2009 i686
$ gcc --version
gcc (Debian 4.5.3-5) 4.5.3
$ gcc -Wall foo.c
$ ./a.out # as expected
RETURN: 0xf
WTERMSIG: 15
WEXITSTATUS: 0
$ uname -msrv
SunOS 5.10 Generic_144489-06 i86pc
$ gcc --version
gcc (GCC) 4.6.0
$ gcc -Wall foo.c
$ ./a.out # unexpected
RETURN: 0xd000
WTERMSIG: 0
WEXITSTATUS: 208
$ suncc -V
cc: Sun C 5.9 SunOS_i386 Patch 124868-15 2010/08/11
$ suncc foo.c
$ ./a.out # same error
RETURN: 0xd000
WTERMSIG: 0
WEXITSTATUS: 208

I might write a documentation patch in a few days if nobody
beats me.
